How can I work out the postions (1st, 2nd, 3rd, 4th,...) based on the scores?
I would like an expression to return values of 1, 2, 3, 4,... Which i will use to change the Y position of a pre Comp in the main comp.

I've got loads of these boards to do so was hoping I could just build one. Duplicate it, Enter the scores and have the contestants re-ordered automatically :)

Here's an expression that may help you. Be sure to read the comments and do something with the value at the end:

// scores go here!
scores = [300,800,200,500,0,500];

// create a new array of arrays which will hold hold the scores and their original index in the array.
scoresIndices = new Array(scores.length);
for (i = 0; i < scores.length; i++) scoresIndices[i] = [scores[i],i];

// finally, you can get the indicies in sort order. The first will be scoresIndices[0][1], the second will be scoresIndicies[1][1]
// the third will be scoresIndices[2][1] and so on
scoresIndices[0][1]
